Surface and motion regime
Different designs are rated for different operating conditions: from slow movement under high load to repeated oscillating motion. The contact-pair material, lubrication, and actual operating regime are of key importance.
Operating regime
- Type of motion: rotation, oscillation, or translation.
- Load and its direction.
- Sliding speed.
- Frequency of operating cycles.
- Lubrication and serviceability.
- Ambient temperature.
- Contamination and environmental exposure.
- Service-life requirements for the contact surface.
